Hi larry21, [a] slope = 4, points (1, -3) and (x, y) \(\displaystyle \frac{y_2-y_1}{x_2-x_1}=4\) \(\displaystyle \frac{y- ^-3}{x-1}=\frac{4}{1}\) \(\displaystyle y+3=4 \:\: and \:\: x-1=1\) \(\displaystyle y=1 \:\:and\:\:x=2\) \(\displaystyle (2, 1)\) Do you think you could follow these steps and complete the others?
